Its applications include soil compacting for road, embankments and reservoirs as well as backfilling for gas pipelines, water pipelines and cable installation work. The impact force of the MT-74F levels and uniformly compacts voids between soil particles to increase dry density. Circular motion is converted to create impact force. The MT-74F tamping rammer develops a powerful compacting force at the foot of the rammer. To maintain optimum performance, proper operation and service are essential. Construction of Tamping Rammer The Mikasa MT-74F is equipped with an air cooled, four-cycle gasoline engine. Transmission of the power takes place by increasing the engine speed to engage the centrifugal clutch. Rammer Gearbox and Spring Cylinder The Mikasa MT-74F uses an oil bath lubrication system. Always check the oil level through the oil level sight glass at the rear of the tamper foot. Controls Before starting the MT-74F Tamping Rammer identify and understand the function of the controls.
